Solve using elimination.
A. x = 4, y = 2; x = 2, y = 4; x = -4, y = -2; x = -2, y = -4
or (4, 2), (2, 4), (-4, -2), (-2, -4)
B. x = -4, y = -2; x = -2, y = -4 or (-4, -2), (-2, -4)
C. x = 4, y = -2; x = 4, y = 2 or (4, -2), (4, 2)
D. x = 4, y = 2; x = -4, y = 2 ; x = 4, y = -2; x = -4, y = -2
or (4, 2), (-4, 2), (4, -2), (-4, -2)
